Components of the MEC 600 Jr Reloading System
The MEC 600 Jr reloading system comprises several key components working in harmony. The core is the robust plastic frame‚ providing a stable platform for operation. It features a primer feed system‚ ensuring consistent primer delivery‚ and a powder die for accurate charge measurement.
Essential elements include the case holder‚ securely gripping the shotshell during the process‚ and the wad guide‚ facilitating precise wad placement. A crimp die shapes the final shell‚ creating a tight seal. The system also incorporates a spent primer collection tray for easy cleanup.
Understanding each component’s function‚ as detailed in the manual‚ is crucial for efficient reloading. Additional parts‚ like shell holders for various gauges‚ may be required. Regular inspection and maintenance of these components‚ as outlined in the manual‚ guarantee optimal performance and longevity of your MEC 600 Jr.
Setting Up the MEC 600 Jr for First Use

Before your initial use of the MEC 600 Jr‚ careful setup is paramount. Begin by securely mounting the press to a stable workbench – stability is key for consistent results. Next‚ familiarize yourself with each component‚ referencing the manual’s diagrams. Ensure all parts are correctly installed and move freely.
Adjust the primer feed system according to the primer size you’re using‚ following the manual’s specific instructions. Calibrate the powder die to accurately measure your desired powder charge. Select the appropriate shell holder for your shotgun gauge and firmly seat it in the press.
A dry run‚ without shells‚ primers‚ or powder‚ is highly recommended. This allows you to practice the reloading sequence and confirm smooth operation. Always double-check all adjustments before loading live components‚ as detailed in the manual. Proper setup ensures safe and efficient reloading with your MEC 600 Jr.
Step-by-Step Reloading Instructions
Following the MEC 600 Jr manual‚ begin by placing a hull into the shell holder. Next‚ operate the press to seat a primer‚ ensuring it’s fully seated and flush with the hull base. Carefully measure and pour the correct powder charge into the hull‚ utilizing the calibrated powder die.
Insert the appropriate wad onto the powder column‚ using the wad guide for proper alignment. Operate the press again to compress the powder and set the wad. Finally‚ place the shot card (if applicable) and shot into the hull.
Complete the process by operating the press one last time to crimp the hull‚ creating a secure seal. Regularly inspect each loaded shell for any inconsistencies or defects‚ as outlined in the manual. Always prioritize safety and adhere to recommended powder charges. Consistent practice‚ guided by the manual‚ will yield reliable reloads.
Primer Insertion Procedures

The MEC 600 Jr manual details a precise primer insertion process. First‚ ensure the primer feed tube is correctly loaded with the appropriate size primers. Verify the primer punch is securely installed within the press. Place an empty hull into the shell holder‚ aligning it with the primer seating mechanism.
Operate the press handle smoothly and deliberately. This action will activate the primer feed‚ picking up a primer and seating it firmly into the hull’s primer pocket. Inspect each seated primer visually to confirm it is flush with the hull base and properly seated.
A partially seated or damaged primer can cause malfunctions or dangerous conditions. Refer to the manual for troubleshooting primer feeding issues. Always wear eye protection during this process. Consistent‚ careful operation‚ as described in the manual‚ is crucial for safe and reliable primer insertion.
Powder Charging Techniques

The MEC 600 Jr manual emphasizes precise powder charging for consistent and safe reloading. Utilize a powder measure calibrated for your chosen powder type and desired charge weight. Always double-check powder weight using a separate scale to verify accuracy‚ as variations can impact performance and safety.
Carefully pour the measured powder into the hull‚ avoiding spillage. The manual recommends a slow‚ controlled pour to ensure complete powder drop. Never substitute powders without consulting a reloading data source and adjusting the charge weight accordingly.
Consistent powder charging is paramount. Regularly inspect your powder measure for wear or damage. Always refer to published reloading data for appropriate powder charges based on your components. Following the manual’s guidance and exercising caution are vital for safe and effective powder charging.
Wad Selection and Placement
The MEC 600 Jr manual details the importance of selecting the correct wad for your specific shotshell load; Wads create a gas seal‚ stabilize the shot column‚ and protect the barrel. Compatibility with your hull‚ powder‚ and shot size is crucial for optimal performance.
Proper wad placement is equally vital. The manual illustrates the correct orientation and seating depth for each wad type. Ensure the wad is seated firmly against the powder column‚ creating a secure gas seal. Incorrect wad placement can lead to reduced velocity‚ erratic patterns‚ and potential safety issues.

Inspect wads for damage before use. Discard any cracked or deformed wads. Refer to reloading data for recommended wad types and seating depths. Consistent wad selection and precise placement‚ as outlined in the manual‚ contribute significantly to accurate and reliable shotshells.
Crimping Procedures for Optimal Seals
The MEC 600 Jr manual emphasizes the critical role of proper crimping in achieving optimal seals for consistent and reliable shotshells. Crimping secures the wad column‚ maintains consistent powder volume‚ and ensures a tight seal during firing. Incorrect crimping can lead to gas leaks‚ reduced velocity‚ and inaccurate patterns.
The manual details the specific crimping settings for various hull types and shot charges. Adjust the crimp pressure according to the reloading data. A uniform‚ consistent crimp is essential. Over-crimping can cause excessive pressure‚ while under-crimping may result in poor sealing.
Inspect each crimped shell for uniformity. The crimp should be even around the entire circumference of the hull. Refer to the manual’s illustrations for visual examples of correct and incorrect crimps. Consistent crimping‚ following the manual’s guidance‚ is paramount for safe and effective reloading.
Troubleshooting Common Issues
The MEC 600 Jr manual dedicates a section to troubleshooting common issues encountered during operation. Frequent problems include primer issues – misfires or primers not seating correctly – often stemming from incorrect primer feed adjustment or worn primer tubes. The manual guides users through diagnosing and resolving these.
Another common issue is powder inconsistencies. This can be caused by a clogged powder die or improper powder baffle adjustment. The manual provides detailed instructions for cleaning and calibrating the powder system. Wad issues‚ like binding or improper seating‚ are also addressed‚ with guidance on wad selection and die adjustments.
Finally‚ the manual covers crimping problems‚ such as uneven crimps or shell sticking. These are often related to incorrect crimp settings or worn crimp dies. Always consult the manual before attempting repairs or adjustments‚ prioritizing safety and proper procedure.
Identifying and Replacing Worn Parts
The MEC 600 Jr manual emphasizes regular inspection for worn components to maintain reloading precision and safety. Key parts prone to wear include primer tubes‚ powder dies‚ and crimp dies. The manual details visual cues indicating wear – such as cracks‚ deformation‚ or excessive play.
